I've had a set of Zoom Carbon Side mirrors tucked away for a while. They're not in great condition with CF needing refinishing and the threaded connector lock nut between the base and mirror corroded.

Getting the CF looking good again shouldn't take too much effort, but I'd like the complete package looking good, and therefore would like to replace the locknut so I thought I'd ask if anyone has had their mirrors apart before I take to it with too much force.
